What Is a Chocolate Tart? 

Also known as a chocolate cream pie, a chocolate tart is a dessert made out of dark chocolate, cream, and eggs that are beaten together and poured into a pastry shell crust. Baked until firm, it is considered to be a type of custard because of its egg-based filling. Similar to custard, chocolate tarts are smooth, silky, and unbelievably rich. However, thanks to the pie-like shell, they’re easy to slice and great for serving! 

Origins of the Chocolate Tart Recipe

The enjoyment of chocolate tarts can be traced all the way back to Colonial times. Crazy, right?! The first printed recipe is believed to be Hannah Glasse’s chocolate tart which was published in The Art of Cookery Made Plain and Easy in 1747. 

Although similar to the chocolate tart recipes we know and love today, the original recipe would have been grittier with a bolder cocoa flavor. This is because the chocolate we use today wasn’t available until the 19th century when machines were invented to grind pure cocoa and sugar began to be included in the refining process. 

In addition, you might be surprised to learn that Glasse’s chocolate tart recipe included rice flour. During that time, rice flour was a common thickener. Today, cornstarch is more commonly used as an effective way to achieve a thick, smooth texture. Either way, the dessert has always been loved and continues to remain extremely popular today!

Ingredients You’ll Need

For this chocolate tart recipe, we took classic recipes and spruced them up with the addition of crunchy hazelnut and a chocolate crust! 

Crust

  • Oreo Cookies – Not found in most tarts, we love to double the chocolate flavor with a cookie crust! You could also experiment with different Oreo flavors if you’d like. 
  • Toasted Hazelnuts – These add extra flavor and a bit of crunch. 
  • Salt – Enhances the rest of the ingredients. 
  • Unsalted Butter – This is crucial to combine the ingredients and create a rich flavor and crisp, crumbly texture. 

Filling

  • Dark Chocolate – Make sure you use high-quality chocolate that’s at least 60% cocoa. 
  • Heavy Cream – Forms a smooth texture and makes for an even more decadent flavor. 
  • Sugar – Regular granulated sugar helps take some of the bitterness out of the chocolate. 
  • Butter – Unsalted butter helps create a rich flavor and contributes to the smooth, silky texture. 
  • Vanilla Extract – Pure vanilla extract enhances the rest of the ingredients. 
  • Hazelnut Butter – Feel free to use a store-bought option, or make your own

Topping

  • Hazelnuts – Raw hazelnuts are chopped into pieces. 
  • Unsalted Butter – This is melted down and used to coat the nuts. 
  • Light Brown Sugar – Combined with the butter, this forms an almost caramel-like coating that clings to the hazelnuts making them crunchy and sweet.

  • Raspberries
  • Strawberries

How to Make This Hazelnut Chocolate Tart Recipe

Chocolate tarts look super gourmet and hard to make, but the process is a breeze! 

  1. Prepare the Crust. Pulse the Oreos and hazelnuts in a food processor until they’re finely ground. Add the salt and butter, and pulse again just until the ingredients are moist. Press the mixture into a tart pan. Bake until it is browned and set, and let it cool. 
  2. Boil. While the crust cools, add the heavy cream, sugar, and butter to a small saucepan. Bring the ingredients to a low boil. 
  3. Mix. Remove the pan from the heat, and pour the mixture over the chocolate in a medium-sized bowl. Let the ingredients stand for 1 minute. Then, stir until everything is melted and smooth. Stir in the vanilla and hazelnut butter. 
  4. Chill. Pour the filling into the Oreo crust, and place it in the fridge to set. 
  5. Create the Candied Hazelnuts. Melt the butter, brown sugar, and salt in a saucepan over medium heat. Add the chopped hazelnuts, and stir until they begin to become fragrant and are lightly browned. Remove the pan from the what, and transfer the nuts to a silicone mat or parchment paper to cool. 
  6. Top. Sprinkle the candied nuts and extra sea salt flakes on top of your tart, and enjoy!
